Reasons Why DNS Protection is Important For Small Offices Too And Not Just For Corporate Headquarters

Submitted by admin on Wed, 02/08/2017 - 00:00

With the evolution of technology, the world is more unified than ever via the internet. It is the largest portal for exchange of data in the universe. It allows us to connect with anyone across this whole wide world. Just as good cannot exist without evil similarly the internet can never have its perks without having downsides. People of ill intent use this high reach ability of the internet to hack into Domain Name System (DNS) of companies and steal their business ideas.

What is DNS?

The Domain Name System (DNS) is used to convert Internet domain and host names to IP addresses.

The Internet and other large private Internet Protocol (IP) networks count on the Domain Name System (DNS) to help direct data traffic. The DNS contains a distributed database of network names and addresses, and it also provides methods for computers to remotely query on maintained the database. DNS is also often referred as the "phone book of the Internet”.

How Is It Vulnerable?

Stories of DNS getting hijacked are appearing in the news way too often. Hijacking enables a hacker to gain access to the DNS server records for a targeted Web site and corrupting them to redirect visitors to some other site instead. When an Internet user visits a hijacked site, the DNS instructs their browser to request data from the fake location.

The attackers do not necessarily need to break into the DNS itself but can compromise the domain's hosting service by impersonating as Web administrators.

How To Detect DNS Hijacking?

Ping utility is used to detect if your DNS was hijacked. If a domain that does not exist is pinged and it resolutes, then it indicates that your ISP is hijacking your DNS traffic.

DNS hijacking can also be confirmed by another way which is to change the DNS address on a device which you use to 0.0.0.0 and 0.0.0.1. If you find that that your Internet is still working and you can open up web pages normally, your DNS traffic hijacked.

How To Prevent DNS Hijacking?

The Domain Name Security System Extensions (DNSSE) was formed by the Internet Engineering Task Force to prevent DNS hijacking.
DNSSEC was designed in order to protect applications from using corrupted DNS data, which are created by DNS cache poisoning. The answers from DNSSEC protected zones are all verified by digital signature.

Using digital signature, a DNS resolver can check if the information is identical to the information published by the regional owner and served on an authorized DNS server. Although protecting IP addresses is the immediate concern for many users, DNSSEC can also cater to protecting any data published in the DNS, which may even include text records (TXT); mail records (MX), and can even be used to strip out any other security systems that publish references to cryptographic certificates stored in the DNS.

Why Is DNS Protection Important?

DNS protection is of cardinal importance for both small offices and corporate headquarters as the there is no knowing which one might be attacked next. Once your DNS is hijacked all your company and clientele information is exposed and this is something no company how small or big it may be can afford to do. Protection of DNS is like protecting the contents of your personal phone and is as important as your DNS might contain a lot of clientele personal information, which you cannot afford to let loose.

Thus in this advance age of computing, DNS security is of utmost importance and should be viewed in lackadaisical approach. It is important to invest on a good DNS protection service as the risks of losing is a lot imminent in this case. This is what makes DNS protection so cardinal for any office or business.
